Title: An Instrument and a Technique for Field Determination of the Modulus of Elasticity, and Flexural Strength, of Concrete (Pavements)
Author(s): Bartlett G. Long, Henry J. Kurtz and Thomas A. Sandenaw
Publication: Journal Proceedings
Appears on pages(s): 217-232
Abstract:An instrument for determination of the dynamic modulus of elasticity of concrete, in situ, is described. Test results are represented which show (a) the com- parison of test values of E, obtained by various older methods, with that obtained with the new instru-ment; and (b) the relationship of such values to the flexural strength of concrete. It is concluded that adoption of the new method and technic is justified, and that widespread use of the new instru- ment would eliminate the necessity for casting field specimens during construction (except perhaps for day-to-day control purposes) or of removing costly samples from completed works. A method for determining the thickness of concrete pavements is briefly discussed. A rather extensive bibliography is included.
